New King James Version (NKJV)
Numbers 9
17 Whenever the cloud was taken up from above the tabernacle, after that the children of Israel would journey; and in the place where the cloud settled, there the children of Israel would pitch their tents.
18 At the command of the Lord the children of Israel would journey, and at the command of the Lord they would camp; as long as the cloud stayed above the tabernacle they remained encamped.
19 Even when the cloud continued long, many days above the tabernacle, the children of Israel kept the charge of the Lord and did not journey.
20 So it was, when the cloud was above the tabernacle a few days: according to the command of the Lord they would remain encamped, and according to the command of the Lord they would journey.
21 So it was, when the cloud remained only from evening until morning: when the cloud was taken up in the morning, then they would journey; whether by day or by night, whenever the cloud was taken up, they would journey.
22 Whether it was two days, a month, or a year that the cloud remained above the tabernacle, the children of Israel would remain encamped and not journey; but when it was taken up, they would journey.
23 At the command of the Lord they remained encamped, and at the command of the Lord they journeyed; they kept the charge of the Lord, at the command of the Lord by the hand of Moses.
Numbers 10
1 And the Lord spoke to Moses, saying:
2 "Make two silver trumpets for yourself; you shall make them of hammered work; you shall use them for calling the congregation and for directing the movement of the camps.
3 When they blow both of them, all the congregation shall gather before you at the door of the tabernacle of meeting.
4 But if they blow only one, then the leaders, the heads of the divisions of Israel, shall gather to you.
